GaEAsn-DISPENSING DEVICE.

Application filed March 1,

To a7] zczomit 'may concern.'

Be it known that I, JAMES H. MoNTGoM- miY, a citizen of San Francisco, in the county of San Francisco, State of California, have invented certain new and useful Improvements in Grease-Dispensing Devices, of which the following is a description, reference being had to the accompanying drawing and to the figures of ref- 10 erence marked thereon.

This invention relates to new and useful improvements in grease dispensing devices, and more particularly to a devicewhereby grease received in commercial barrels or receptacles may be dispensed directly from the receptacle or barrel in which itjis received. l

The apparatus herein disclosed is an improvement in the construction set forth in my prior Patent No. 1,338,519, granted April 27, 1920, wherein a truck is provided with a receptacle holder adapted to receive directly thereon a barrel of grease so that the grease is fed by its own weight from the open end of the barrel into the receptacle holder from which it is adapted to be forced out through a distributing nozzle on .the holder by means of a manually operated piston. In order to place the barrel in position on the receptacle holder of this truck, it is necessary to rst knock the head out of the barrelto invert they same, and then' tc osition it on the holder of the truck.

ne of the objects of the present invention is to provide a mechanism including a receptacle holder which can be clamped directly to the barrel after the head is knocked therefrom, which holder is constructed and arranged to be lifted with the barrel on to the truck and then inverted so that the lubricant will be fed downwardly by gravitylto' the discharging nozzle, from which it is forced by a manually operated piston member.

Another object of this invention consists in providing a truck and hoisting mechas nism thereon constructed and arranged so that the truck may be moved into position whereby the hoisting mechanism may be connected to the barrel for liftingthe barrel from the floor into a position so that it can be inverted forthe purpose hereinbefore set forth.' i

Another object ofl this invention residesg` in the novel manner of arranging the barrel 1921. serial 110.4455733.

hoisting mechanism with" the movable barrel truck.

v Still another object of this invention relates to the new construction of the barrel top closing member carrying the distributing nozzle, and the member for discharging the lubricant from thebarrel through the nozzle. i I

Yet another feature of this invention resides in the peculiar construction of the reciprocable piston for feeding the lubricant through the nozzle, wherebyl the minimum resistance is otl'eredto the back or idle stroke of the piston. y

These and other objects will in part be obvious, and will in part be hereinafter more fully disclosed.

Referring more particularly to the accompanying drawings Figure 1 is an elevation, lpartly in section of the device inverted and seated on the truck Fig. 2 is a plan view partly in lsection of Fig. 1;'

Fig. 3 is a side elevational view of Fig. 1, taken from theoperating side thereof;

Fig. 4 is .a detail view of the improved piston showing the manner of forcing the ylubricant therethrough Figures 5 and 6 are end perspective views 85 'of the piston disks;

Figures 7 to 9, inclusive, are detail views partly in two sections of the barrel hoisting mechanism, and

Figures 10 and thereof. f

In general, the invention comprises a mobile truck or platform, preferably mounted on wheels, provided with spaced uprights formed with means thereon for vertically hoisting a 'barrel or other commercial grease container from a floor into a freely suspended position above or on the platform. The platform or truck is constructed so that it can be wheeled into position so that these hoisting arms can be disposed on opposite sides of the barrel.k In addition, a closure is provided, which closure is adapted to tightly lit over `that end of the barrel which has lll are modifications 90 .had the head knocked out, and means is provided for clamping this closure to the barrel and to the hoisting mechanism so thatthe barrel and the closure will thereafter move as a single unit. The closure is pro` videdwith a cylinder and piston workable this truck 3 is provided with an operating handle 4 for drawing it into position. The two spaced rearward arms 5 and 6 are pro vided with vertically extending columns 7 cand 8 forming the standards for the hoistmg mechanism. As shown clearly 'in Figures 7 to 11, each one of these columns 7 or 8 is bolted in any suitable manner to the.

main frame of tlie truck and forms a suitable bearing for a vertically extending threaded shaft 9 suitably journaled'therein and adapted to receive the internally threadedblocks l() provided with open-ended recesses 11 on their upperV inner faces for freely receiving the heads 12 of bolts 13 threadedly engaging saddles .14 of the clamping mechanism hereinafter described. In order to hold the blocks 10 in position, the columns 7 and 8 are provided with Suitable slots 15 to receive fastening bolts 16 threading into the blocks 10. The lower end of each of the shafts 9 is provided with bevel gears 17 meshing with similar gears 18 on orizontally arranged shafts 19 journaled in the base of the truck. The inner ends of these shafts 19 are provided with intermeshing bevel gears 20 and 21 so that they may be operated from a common source. Tn--the present case, the extension22 is preferably squared at the-ends in order to receive an ordina crank handle. By means of this neat an compact construction, the threaded shafts 9 are simultaneously rotated tov adjust the blocks 10 vertically. o'f their columns 7 and 8.

The mechanism for feeding the lubricant i from the barrel to its source Vof distribution comprises an integral cover and pump mechanism consisting .of a cap or barrel closing cover 23 provided with a circumferential sealing washer 24 upon which seats the barrel or container rim to prevent the lubricant from leaking at this point. This sealing` rim 24 is preferably seated in the circumferential recess formed in the cover 23 by the circumferential spaced flange 25. This cover is provided with a closed end 26 preferably cylindrical in shape, and apertured at its opposite ends as at 97 and 28 to receive a discharge nozzle or @pana 29 and a bearing bloei; 35'. Vwithin this cyhndrical portion of the capv 23 is mounted the feed cylinder 311 slottedV as at 32 to provide a communication with the in inder is provided with a bearing block 35 A threadedly engaging the cylinder 31 and the aperture 28 in the cover 23. Adapted to 'reciprocate in this cylinder is the piston member operated by means of a piston rod 36 passing through the bearing block 35 and formed at its outer end with a detachable connection 37 on the lower end of the manually` operated lever 38. The preferred form of making this connection detachable is by means of the usual slot and pin connection. As a means`for forming a bearing for the upper end 39 of the lever for operating the piston, there is provided a bracket member 40 fastened to the side of the cover in any suitable manner, which bracket meme ber 40 is provided with spaced bearings 41 to receive a shaft 42, and a rigid extension 43 to provide afurther journal for the shaft 44 on which the lever 39 is pivotally mounted. The brake member consisting of spaced downwardly depending arms 45 is journaled on the shaft 42 and hangs freel therefrom so as to engage theioor to ho d the movable platform from movement in one direction.

- The piston itself comprises two relatively movable disks 46 and 47, the first being rigidly connected to the piston rod 36 and the latter being mounted to slide freely thereon toward and away from the first-piston disk 46, These respective disks are provided with non-registering slots or apertures 48 and 9.49v

which, when the members l,are spaced apart, permit thefree flow of lubricant through one disk acrossthe space interveningand through the slot in the other disk. Itwill readily be seen from this construction, that when the disks abut one another, these non-registering, apertures will prevent the flow of lubricant therethrough, and will act as a solid imperforate piston face to force the lubricant which is in fro'nt of the piston outwardly through'the discharge nozzle 23 to the discharge nozzle 29. This forward movement ofthe lubricant occurs on the forward stroke and after the disks are brought together. On the return stroke, the lubricant which has been fed by gravity into the cylinder 31 from the barrel and which is behind the piston, can flow through these openings 48 and 49 inasmuch as the disks have now become spaced on the rearward stroke, so that a ist the backward reciprocations of the piston, and at the same time, the maximum of grease or lubricant is fed in front of the pistons to be discharged onthe next forward stroke. As a means for preventing the apertures 48 and 49. of these respective disks 46 and 47 from becoming alined, there is provided a guide pin 50 secured rigidly on the disk 46 and passing freely through the aperture in the disk 47.

The clamping means for securing the cover 234to the barrel land for securing it to the threaded bolt 13 of theV hoisting mechanism will now be described. This mechanism in one form, comprises the twosaddles 14, provided with attached links 51 and 52, to which are linked in any suitable manner, the clamps 53 and 54 adapted to engage the under side of the rim of the cover 31. These rods 51 and 52 are arranged'in pairs on opposite sides of the barrel or container. Each saddle f 14 has a pair of such rods or links connected thereto so that the barrel cover 31 is clampedat four points. The opposite ends of the saddles 14 are provided with any suitable connections, preferably in the form of iml threaded bolts 55 which receive the clamps 56 having threaded adjustable connection to the bolts. The saddles 14, in turn, have a plurality of spaced apertures 57 for adjustably receiving the threaded ends of the bolts 13, which bolts, as before described, are re ceived in the sockets or recesses 11 of the adj usting block 10. By means of these threaded apertures 57, the saddles 14 may be attached at any portion of the barrel or container, that is, the pivotal point 13 may be disposed at the portion of the barrel intermediate its ends at a position higher up. In this manner, the pivotal point on which the barrel turns may be changed. S6 also, this series of apertures 57 provides a greater range of 'adjustment of the clamping members.

cesses Vor slots 11 so that the saddles .are connected to the hoisting mechanism. The crank handle applied to the end 22 of the shaft 19 journaled in the base is then rotated, and the hoisting blocks 10 raised so that the barrel is lifted from the floor on to the truck and clear of the base thereof. The lever 39 is then swung to extreme rear position which permits the free rotation of the barrel to invert the Sallie. The hoisting mechanism is then lowered so that the barrel with the feed cylinder lowermost as in Fig. 1, will then rest on the truck platform. In this position, if desired, the stop 58 attached to the cover 31 will engage in the recess 59 in one of the columns to prevent any forward movement of the barrel. This .is the locking mechanism. When it is desired to feed the lubricant from the barrel, the hand lever 39 is reciprocated so that, the lubricant, which is gravity fed by its own weight from the barrel through the slot 32 of the cylinder 31, is forced out of the discharge nozzle 29 on the forward movement of the piston. The brake member 45 prevents the rearward movement of the movable platform. The forward movement of the platform is prevented in view of the fact that the truck is placed against the automobile while the lubricant is being fed into the opening therein.

It will be obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

lHaving thus described the invention, what I claim as new and desire to secure by Letters-Patent, is-
